there are basically 2 things that can be done; pharmacological or surgical/therapeutic. Pharmacological means using mild pain killer or use of special tooth paste to cure the condition. this will work only if the causative agent is mild/temporary. If the causative agent is not temporary (caries, TMD, periodontal issues etc) you need to seek treatment. Only a visit to a dentist -visual and radiographic check up -will help determine what is the causative agent. Being a med professional I hope you can appreciate the answer and the attention you require and I hope you will visit a specialist for further action
